I confess, I hadn't considered anything quite so bold as reading the whole
of the text into Lua and then processing it back out. I suppose I was
expecting one of the true TeXperts to offer suggestions involving
\appendtoks ... \to \everypar.

I also realized that I forgot to mention that I want to be able to do this
all while using the ConTeXt project/product/component support.

Any other suggestions on how I could process unmarked paragraphs in Lua?
